Donald is curious about finding the answer to this question.

"Given a promising planet devoid of life in a habitable zone, say with a profile like early Earth, what would a terraformer do to create a viable, self sustaining planet full of life. Is it as simple as introducing one initial successful asexual cell, and wait? Or can the process be accelerated by sequential introduction of appropriate organisms, and which ones in which order and WHY?"
